I had the opportunity to play through the game at exhibitions and meet up with the devs.

There are a lot of levels and it's a pleasure to solve them all. The difficulty ramp is well laid out. The levels are tricky and clever, some really need heavy brain power.

What I like about this laser-puzzle game is that it is based on hexagons (and not squares as most of the other ones) and that it is based on physical simulation of light. You can collect light between two mirrors and have fun with it :)I played several laser-based puzzle games but this one is the most tricky one and I enjoyed the most so far.

This puzzle game can be enjoyed by all puzzle fans, but I think hardcore puzzle fans will have the most fun, as latter levels become quite tricky.

I fully recommend this game to any hardcore puzzle fan.

Small gameplay trick from me:- Think from the exits towards the light-sources. Makes solving the puzzle easier.- If you have no idea what to do, remove all the parts and begin from scratch with only the fixed parts remaining.

On another note, I met the devs of this game and they are really nice guys. Even if you don't like hard puzzle games maybe think of supporting the devs anyhow.

Besides receiving a test key, I had more than enough possibilities to play this game, since this has been shown on numerous occasions e.g. at Fantasy Basel or Zurich Game Show.

It's a really neat puzzler that challenges you with all kinds of different mechanics that revolve around lasers (and who doesn't like Lazors). For some reason, although all of the mechanics are based on equally real optic principles, my brain likes some of the mechanics much more than the others. For example, I really like the prism mechanic of splitting white light into its base components, but I still get confused about the filters sometimes.

The puzzles themselves vary from being relatively simple to requiring serious (and fun) thinking. Sometimes, there is also one I just cannot solve, and my brain gives up (however, I tend to do that in a lot of puzzle games).

All in all, if you're looking for a fun and challenging puzzle game that you can also pick up casually, I would definitely recommend this.

This is what I exactly want all the time, the best traditional light puzzle game I ever played.Simple but stylish graphic.Tricky but elegant puzzles.Typical but colorful game mechanics.Well-made to unleash the very potential of a light puzzle game.

A little suggestionThe shards reward in the some level may need adjustment, where player has no way to get less than 3 shards, for the number of mirrors that game provides is only the minimum, but sometimes the game still have the setting of 2 or 1 reward if the player could use more.

After about two hours in, I'm a little over halfway done with the first of four puzzle packs. Admittedly, I'm not the brightest crayon in the box, so others might progress faster, but it's still hours and hours of entertainment. Not a bad deal for the price.

This game caught me by surprise. I went in expecting "just another light-beam" game, and was surprised by the depth and complexity of the levels.

The game takes simple tools, introduces them in a way that lets you know precisely what they do, and then ramps up the difficulty once you've got the idea. While it is by no means an "easy" game - The difficulty comes from actual puzzles and never from not understanding what is expected.

Since I bought the game, another free 72 levels were added as free DLC (Level Pack 4), with again - new tools which are easily understood but result in some seriously difficult puzzles. The developers for this are very open and have helped fix unintended solutions and other problems very quickly.

Ultimately it's a great game and I've enjoyed it. 10/10, easily the best "light-beam" game I've played.

So, I only wanted to check it out for a minute but then found myself hooked with that "just one more" feeling. That's a good sign, isn't it? I'd recommend this game to anyone that enjoys abstract puzzles.

Visuals/AudioThe presentation is very smooth and responsive. While the graphics are kept simple, they communicate all the necessary info and there's a polished minimalist quality about them that's pleasant and unobtrusive. The same goes for the audio (i.e. sound effects and music/soundscapes): They provide a pleasant backdrop that doesn't distract you and helps you get into that focused state of mind you'll no doubt need to solve the tricky puzzles.

GameplayWhile I haven't played that far, I know from seeing the game's later stages at various game shows that it includes a nice range of interesting mechanics that will tickle your brain. So far playing at home, the difficulty ramp-up and the pace at which new concepts are introduced seem good. Personally, what I find a great idea is that you don't have to solve all the puzzles to progress, you can skip them and try other ones of the same level/stage (The Talos Principle did something like that, too). This helps alleviate one of the greatest frustrations of linear puzzle games: getting stuck.

Thematically it's also cool that as far as I can tell, they stick to realistic behavior of light/lasers (except where visual communication necessitates abstraction), e.g. in the way you combine laser colors to create new colors.

Full disclosure: I know the developers and have seen the game at various game shows. To give you the relevant context: As an indie developer myself, I'm really strapped for cash, so even though I'd love to support all my dev friends, I am not in the habit of buying their games (it would just be too many) unless I know I'm going to play and enjoy them.

All in all a pretty neat and challenging game. The 2D perspective makes it more intuitive to follow how your actions will affect the lasers then some of the recent 3D laser based puzzle games. It does a good job of introducing new mechanics though sometimes it does feel that there are more puzzles then necessary dedicated to a particular mechanic. There are some mechanics that you think you understand initially but then later get put into a situation that defys your expectation that is always nice. (Still trying to figure out the full rules of the colored dots). Puzzles with multiple ofthe same colored laser can sometimes get confusing to

If you enjoy puzzle games/Achievement hunting I'd highly recommend picking it up. If you are more of a casual gamer you might lose interest within the first 30-40 levels as the general gameplay is very repetitive however they spice it up with adding new game componets into the mix and making things more challenging.

A very lovely made puzzle game with a tiny touch of science.I absolutely recommend this game to every fan of puzzle games.Whether you can remeber the RGB-combinations to get the colors magenta, cyan and yellow (I can't) - it doesn't matter!By - either as an experiment or because you know the right way - combining the different colored light beams, you will solve level by level (okay, you also have to put the mirrors in the -or any- correct spot).

One of the things I like in this game is, that there are several ways to solve a level. I honestly never thought that a game about light is entertaining, but it is!
